`Link` does not fire `onClick` / `onPress` when activated via keyboard (Tab + Enter), causing full page reload with third-party routers

### Provide a general summary of the issue here

When a React Aria `Link` is focused via `Tab` and activated via `Enter`, neither `onClick` nor `onPress` is fired. This prevents 3rd-party routers (e.g. TanStack Router) from intercepting navigation and calling `e.preventDefault()`, causing the browser to fall back to native `href` navigation — resulting in a **full page reload** instead of SPA client-side navigation.

Mouse click works correctly: both `onClick` and `onPress` fire as expected.

### 🤔 Expected Behavior?

Pressing `Enter` on a focused `Link` should fire both `onClick` and `onPress`, identical to mouse click behavior.

```tsx
console.log("onClick fired")} // ✅ should fire on keyboard Enter
onPress={() => console.log("onPress fired")} // ✅ should fire on keyboard Enter
>
Development

```

Third-party routers that rely on `onClick` + `e.preventDefault()` (e.g. TanStack Router) should be able to intercept the event and perform client-side navigation without a full page reload.

### 😯 Current Behavior

When the link is activated via **keyboard** (`Tab` to focus → `Enter` to activate):

- `onClick` is **not fired** ❌
- `onPress` is **not fired** ❌
- Browser follows the `href` natively → **full page reload** ❌

When activated via **mouse click**:

- `onClick` fires ✅
- `onPress` fires ✅
- SPA navigation works correctly ✅

This affects both integration approaches documented in TanStack Router's custom link guide:

```tsx
// Approach 1 — createLink()
const CustomLink = createLink(AriaLink);
Development

// Approach 2 — _asChild (internal API)

Development

```

### 🖥️ Steps to Reproduce

**Plain React Aria reproduction (no TSR):**

1. Open: https://stackblitz.com/edit/skmzpfdr?file=src%2FExample.tsx
2. Open the browser console
3. Click a link with the **mouse** → observe `onClick` and `onPress` logged ✅
4. Focus the same link with **Tab** and press **Enter** → observe nothing logged ❌

**With TanStack Router integration:**

1. Open: https://stackblitz.com/edit/vitejs-vite-2xxlupse
2. Click a link with the **mouse** → SPA navigation, no page reload ✅
3. Focus a link with **Tab** and press **Enter** → full page reload ❌
